Author doesn't seem to know what a wire frame is. And doesn't seem to have any concept of how UI/UX should be done.
Wireframes are typically used for determining how much of each screen something will take up. After that you move to a Mock up.
You don't need to see video play to know that the video is going to be too small if the Logo is 1600x800 on the page.
A wire frame should be more like the pencil sketch or white board image that you use to talk about what is going to where, and to be used as a "map". It doesn't convey what things will really look like as much as give you an idea of where things are and how much real estate they take up.
Think of a wireframe like a relief map. It tells you how tall the hill is, and where the canyon is, not how beautiful it will be or what color. A blue print tells you where the studs in the building will go, but you get a better picture of how the building will look from a little Styrofoam model. They are both important, but they aren't the same thing.
